Define a function that when passed two Strings, each holding a (possibly very very long integer) as a String, returns the sum of the two numbers, as a String. You may assume that both numbers are positive (more than zero). NOTE: The strings can be very very very very long so don't even try to convert them to integers. add_strings('49631058602853065830185206186591385964821306890681', '934593852935839589589458395835234589248295893578295673962769763976967395475') → '934593852935839589589458445466293192101361723763501860554155728798274286156' add_strings('1', '99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999') → '100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000' add_strings('99999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999', '1') → '100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000' ...Save, Compile, Run (ctrl-enter) |
